Jason Trawick to Share Legal Control Over Britney Spears

Britney Spears”s father is taking an extra step in bonding with his future son-in-law.

Jamie Spears is asking a court to add Jason Trawick as a co-conservator over his pop star daughter, a source confirms to us.

Trawick will only have shared legal control over Spears”s general well being – not her finances, according to the source. In general, a conservator can make decisions over a person”s food, clothing and medical care. But Spears has plenty of personal freedom and the conservatorship is just a formality, another source previously told us.

“This is a very unusual situation, because generally you don”t see conservatees get married,” says Jeffrey S. Cohen, an L.A. probate attorney not involved with the case. “This could be a sign that the couple”s wedding is around the corner.”

Adds Cohen: “This is probably a compromise between Britney, her father and Trawick to get the marriage off on the right foot. Obviously, her future husband needs to have a say in her well being.”

Jamie Spears has held legal control over his daughter and her multimillion-dollar fortune since Feb. 2008 after the singer suffered a psychological breakdown.

The conservatorship will be lifted only after a judge is convinced, on the advice of Spears”s doctors, that she”s healthy enough to manage her own affairs.
